Most of the products photos and data on https://world.openfoodfacts.org is crowdsourced by users who scan product barcodes, use the Open Food Facts mobile app to send photos of the product, ingredients and nutrition facts, and the Open Food Facts web site to input the corresponding data. This project aims to find errors in data entered by users, and to speed up data entry by automatically classifying products or making suggestions to contributors. | Most of the products photos and data on https://world.openfoodfacts.org is crowdsourced by users who scan product barcodes, use the Open Food Facts mobile app to send photos of the product, ingredients and nutrition facts, and the Open Food Facts web site to input the corresponding data.
